Fight against cereal rusts enters a new era
The Australian Cereal Rust Control Program has entered a fifth phase, developing knowledge and technologies to better understand the pathogen and improve rust resistance in cereals. Here is a summation of the new work in progress.

FAW’s ability to adapt putting more crops at risk
The word ‘challenge’ dominated talk at the National Fall Armyworm (FAW) Research, Development and Extension Symposium in Brisbane in April. It is now in Victoria and it has also confirmed its presence in New Zealand. It is one of the most challenging and confronting pest management issues for growers.

Automated detection takes guesswork from fungicide response
BioScout’s next-generation spore traps leverage automated microscopy and machine learning to provide near real-time insights into airborne fungal disease threats. This allows growers to take targeted action and optimise spray programs, including through a newly launched automated surveillance network

Disease outlook and managing increased risk
GRDC Research Updates have foreshadowed a heightened risk of disease in 2024, while providing advice on the steps to take to minimise impact on grain yield. Providing a cereal disease outlook, plant pathologist Dr Grant Hollaway from Astute Ag said there was risk of yield losses from diseases including Septoria tritici blotch in wheat, net form of net blotch in barley and rust pathogens in both cereals.

Barley grass stripe rust variants characterised by increased virulence
BGYR (barley grass stripe [yellow] rust), was first detected in Australia in 1998, predominantly affecting wild barley grass weed species. Through comparative greenhouse studies, the Plant Breeding Institute established that the BGYR+ variant has shown increased virulence on several barley varieties at seedling growth stages.

The AFREN creed
Creeds can be powerful beliefs to live by and when it comes to dealing with fungicide resistance the Australian Fungicide Resistance Extension Network have developed the powerful Fungicide Resistance Five. A checklist, underpinned by science, this creed is a reminder as to how to mitigate the threat of resistance. Growers are encouraged to keep it top of mind.

Decision support tools aid disease management decisions
A suite of handy mobile devices is equipping growers and advisers to be better informed about crop protection practices. Through improving these management practises the risk of fungicide resistance can be reduced.

From the shelf to field failure: factors driving fungicide resistance
Three factors can drive fungicide resistance risk. Understanding the drivers is vital for risk mitigation and to this end a useful matrix is available to determine the overall risk of fungicide resistance developing. The matrix combines the type of fungicide being used, the risk of the pathogen developing resistance and risky agronomic practices that can drive fungicide resistance.

Out and about with AFREN
A practical service provided by the Australian Fungicide Resistance Extension Network to growers not only provides definitive information on whether they have a disease or resistance issue to deal with, but also enables researchers to discover first-hand which diseases and resistance are emerging on the ground in different parts of the country. This was showcased at the Field Applied Research Field Day at Winchelsea in Victoria in 2023.
